Definitely trust but verify.
I had a 10 year hiatus in the hobby between 1999 and 2005 or thereabouts. Talk about critical years!
I sold off a 100 gal acrylic mixed reef with what had been state of the art crushed coral, drip trays, diatom filters, no skimmer, exterior pump, and only slightly exotic fluorescent lighting and we thought bristleworms were the enemy, we used only dry rock, kalk was exotic, and getting softies to live was a biggie---except we had no trouble with elegance coral; I came back into the hobby 5 years later with aragonite, dursos, submerged pump, kalk/and reactors, metal halide lighting, dosing, water changes, fuge/sumps, skimmers, drilled tanks, and the ability to grow stony coral hand over fist---except elegance. And now we're going to have another major change in lighting, and I may change out my lights. The tech has totally mutated. What we can keep has vastly changed. How we keep it has changed. LFS's that have been in business for decades are not evil---but they may be operating the way they did in 2000.
